Thank-you for your information. It's greatly appreciated! The cardiologist is telling me that my ejection fraction is lower-he never once has mentioned circulation. This is so confusing to me. He makes me feel like he just wants to make money. They are also saying that my afib is making my heart weaker. I have had Afib since 2003 and an Electrophysiologist at Johns Hopkins said I can't have an ablation. I have a CRT-pacemaker. I was always told people can live just fine with Afib as long as they take blood thinner.
